"Origins of the Thunderbird"
"Myth Cryptozoologists like Mark A. Hall, having studied the Thunderbird myths
of numerous tribes, and compared them to (mostly folkloric) accounts of unusually large
birds in modern times, as well as large birds (like the Roc) in other mythic traditions, suggest
that there may well be a surviving species of large avians in America - big enough, apparently,
to fly off carrying small animals or children, as has been claimed in some accounts. (Hall suggests the wingspan of such a species would be several feet longer than any
known birds - certainly bigger than that of the turkey vulture or other identifiable
North American species.) (Hall 1988) Such researchers feel the Thunderbird myth may have
originated from sightings of a real-life flesh-and-blood avian which might be an atavism
from earlier epochs (a quasi-pterodactyl or teratorn, perhaps.)"
Each report brings us more fiction and less science.

From the Los Angeles County Natural History Museum display based on parts of a skeleton of the biggest known bird that ever flew.
Looming over the entrance hall, a black silhouette of Argentavis magnificens spans its wings over 8 m (about 25 ft.) and stands 3.5 m from tip of tail to end of beak.
This is almost twice the size of Teratornis merriami which, until now, had been considered the largest size to which flying avians could evolve.

Also... according to one article (probably seen in "Strange") the Tex-Mex border area has stories of sinister, huge, winged creatures (sometimes without feathers, IOW, echoing the pterodon critters from the dinosauria), which eat carrion as well as live prey, swooping down to pull the dead out of the coffins during graveside services. :')
So how did the "less than 1 kg" Little Eagle kill the moas to begin with?
Huge eagles 'dominated NZ skies'it was driven to oblivion about five centuries ago, just 200 years or so after the first humans arrived... The researchers, led by Professor Alan Cooper from Oxford's Ancient Biomolecules Centre, extracted DNA from fossil eagle bones dating back about 2,000 years... What they showed was that the New Zealand bird was in fact related to one of the world's smallest eagles - the little eagle from Australia and New Guinea, which typically weighs less than 1kg (two pounds). Yet the Haast's eagle weighed between 10kg (1st 8lb) and 14kg (2st 3lb) - between 30% and 40% heavier than the largest living bird of prey alive today, the harpy eagle of Latin America, and was approaching the upper weight limit for powered flight... Nerc says: "Haast's eagle is the only eagle known to have been the top predator in a major terrestrial ecosystem. "They hunted moa, the herbivorous, flightless birds of New Zealand [now also extinct], which weighed up to 200kg (31st 7lb)... Forest fires destroyed its habitat and humans exterminated its food supply. There is also some evidence to suggest the eagles were hunted.
